Test eye scans to choose the right cataract lens power
Part of Eyes & vision clinical trials.
This study is looking at how special eye scans (optical coherence tomography, or OCT) can help doctors calculate the correct power of a cataract lens after you’ve had laser vision correction before. It may help improve how well your new lens matches your eye after prior laser treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are planning cataract surgery and will receive a monofocal (single-focus) lens, including a toric version if needed
- Your cataract lens cannot be multifocal or accommodating (not the “focus-switching” types)
- You previously had laser vision correction (like LASIK, PRK, LASEK, epi-LASIK, or RK)
- You can understand the study and give informed consent
- You can keep your eyes steady so OCT scans work, and you can attend all required visits

This study uses a special eye scanner and artificial intelligence to help doctors pick the right lens implant for cataract surgery. Your eye test results will be used to improve the technology, which could lead to better vision after surgery.
This trial tests a specific cataract replacement lens to see how safe it is and how well it improves vision. If you have cataracts in both eyes and are good candidate for cataract surgery, this lens may help you see more clearly after surgery.
This study looks at how well your vision works and how different cataract surgery lens choices perform. It may help researchers better understand what affects sight after cataract surgery.
This trial tests two different devices that measure your eyes before cataract surgery to see which one helps doctors choose the best lens implant. The goal is to get your vision as close to perfect as possible after surgery.
This trial tests whether artificial intelligence can improve calculations for the lens implant used during cataract surgery. If you're having routine cataract surgery on both eyes, this study might help make your lens power more accurate.
This trial uses an eye scan (OCT) to see if it can predict how well you will see after cataract surgery, compared to your doctor's usual assessment.
